KEG.

sPEcmroATroN forming part of Letters Patent No. 700, 567, dated Ma '2o, 1902.

I Application filed February 24, 1902. Serial No. 95,160. (No model.) I

To all who??? it,Jrmy'omtcerm: I Be it known that I, FRANK X. SCHWAB; a citizen of the United States, residing at Buffalo, in the county of Erie and'State of New. York, have invented certain new and useful Improvements-in Kegs, of which the follow,- ing is a specification.

This invention relates to an improved keg in which the staves are joined to each other by tongue-and-groove connections, said tongues being of equal size throughout and terminating abruptly a short distance from the stave ends, and said grooves'b'eing of equal depth throughout and corresponding in form to the tongues which fit therein. The head parts are alsojoined by similar tongues and grooves.

The object of the invention is to form a keg which shall be absolutely liquidtight and which will stay tight, all of which will be fully and clearlyhereinafter described and claimed, reference being had to the accompanying drawings, in. which Figure 1 is ahorizontal section through a keg on or about line a a,-Flg. 2. V Fig. 2 is a vertical section through a portion of a keg on or about line b b, Fig. 1. Fig. 3 is aplan view of a portion of the head of a keg. Fig. i is a side view of same. Fig. 5 is a section through the head on line a c, Fig. 3. Fig. 6 is a section through one of the staves on or about line cl (1, Fig.8..- Fig. 7 is an inside-view of Fig. 8

Fig. 9 is an inside view of two staves after being bent. Fig. 10 is a side view of one of the staves after being bent.

Referring to the drawings for the details of construction, like numerals designate like parts.

The improved keg is composed of a series of staves, two heads, and hoops. The staves 1 are each made by machinery and are out so that they are of equal size and identicalform. Each stave when first cut to form is flat and has curved side edges 2; A longitudinal tongue 3, of equal size throughout and curved cross-section, is formed integral with the stave and projects from one side edge thereof, terminating near each end of the stave in an abrupt shoulder 4. A longitudinal groove 5 is cut in the opposite side edge, which is of equal depth throughout and correspondingly removable ribs loose in, the grooves with curved shoulders; but neither of these forms are efficient inpreventing leaks of liquid, especially when under pressure,since the curved "shoulders "are only in. engagement when the staves are held closely together and separate from each other when the staves separate, so that the loosening or springing of the hoops, and consequently partial separation of the "staves,will produceinterveningspaces, which serve as outlets'for the liquid contained therein. The advantages of the abrupt shoulders is that the shoulders are in engagement even when the staves become slightly separated from any cause, and thus materially aid in maintaining a'tight' joint,iwhich is of vital importance in a keg of this description designed for holding beer, ale, or similar liquids. A transverse groove 7 is formed on the interior of the stave neareaeh end thereof, which when the staves. are assembled constitntes the annular groove or pocket in which the parts of the head are supported. The tongue 3 and groove 4 of eachstave extend beyond the chime, as shown in Figs. 7, 8, 9, and 10, thereby providing a tight continuous interlocking joint, whichcprevents any leak .through those portions of the-staves between the heads. l I

The heads 8 are each in several parts, which are joined by tongue-and-groove connections similar to those described with reference to the staves, the tongues 9 being of equal size throughout and terminating a short distance from the ends of the head parts in abrupt shoulders 10 and the grooves 11 being of equal depth and corresponding.in. cross-section to the cross-section of the tongues, said grooves also terminating a short distance from the ends in abrupt shoulders12.

In assembling this keg the staves are bent by machinery to givea middle'bulge to the same and also bring the edgesof adjacent staves in close contact throughout and force the tongues into the grooves. The hoops are then forced on the keg ends to hold the staves intheir bent condition and the keg parts in assembled position.

The main advantage of this improved keg is that it is absolutely tight and remains permanently tight. As the tongues and grooves do not extend from end to end of the staves and head parts, but terminate a short distance from the ends thereof in abrupt shoulders, all the staves and head parts necessarily fit perfectly when properly assembled.

Another advantage of this construction is that the meeting shoulders of the tongues and grooves of the staves brings the ends of all the staves in exact alinement.

I claim as my invention- 1. A keg having its staves provided with curved side edges and an integral tongue projecting from one of said side edges of eachstave of equal size and thickness throughout which terminates near each end of the stave in abrupt shoulders, and a longitudinal groove in the other side edge of equal depth throughposed shoulders, substantially as described.

3. A keg having heads, and a plurality of staves with chimes in which the heads seat and interlocking tongues and grooves which extend beyond the chimes and terminate within the ends of the staves.
